15 صفحه اولPorosity Control and Fatigue Behavior in A356-T61 Aluminum Alloy
Much work has been done, in recent years, to characterize the factors that cause porosity in aluminum castings, and to analyze the impact of porosity or microstructural parameters on fatigue life. What has yet to be done is systematically separate out the effects of dendrite arm spacing and largest pore size from each other, and from the underlying chemical and process parameters that influence...
متن کاملInvestigation of the T4 and T6 Heat Treatment Cycles of Semi-Solid Processed Aluminium Alloy A356
The heat treatment cycles that are currently applied to semi-solid processed components are mostly those that are in use for dendritic casting alloys. These heat treatments are not necessarily the optimum treatments. It is shown that a decrease of the solution treatment time at 540 o C from 6 hours to 1 hour does not alter the T4 or T6 tensile properties of the SSM processed A356 alloy. Slightl...

متن کاملThe T6 Heat Treatment of Semi-Solid Metal Processed Alloy A356
A solution treatment of 1 hour at 540 o C provided the best results for rheocast alloy A356-T6. Natural aging has a significant influence on the subsequent artificial aging response of the alloy. Arrhenius-type equations were derived to predict the time-to-peak hardness as a function of artificial aging temperature.
